Genes affected

BRAF (HGNC:1097): (B-Raf proto-oncogene, serine/threonine kinase) This gene encodes a protein belonging to the RAF family of serine/threonine protein kinases. This protein plays a role in regulating the MAP kinase/ERK signaling pathway, which affects cell division, differentiation, and secretion. Mutations in this gene, most commonly the V600E mutation, are the most frequently identified cancer-causing mutations in melanoma, and have been identified in various other cancers as well, including non-Hodgkin lymphoma, colorectal cancer, thyroid carcinoma, non-small cell lung carcinoma, hairy cell leukemia and adenocarcinoma of lung. Mutations in this gene are also associated with cardiofaciocutaneous, Noonan, and Costello syndromes, which exhibit overlapping phenotypes. A pseudogene of this gene has been identified on the X chromosome. [provided by RefSeq, Aug 2017]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP2

Missense variant in the BRAF gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 139 curated pathogenic missense variants (we use a threshold of 10). The gene has 21 curated benign missense variants. Gene score misZ: 3.7208 (above the threshold of 3.09). Trascript score misZ: 4.9447 (above the threshold of 3.09). GenCC associations: The gene is linked to cardiofaciocutaneous syndrome, Noonan syndrome with multiple lentigines, Noonan syndrome, cardiofaciocutaneous syndrome 1, Noonan syndrome 7, LEOPARD syndrome 3, anaplastic astrocytoma, Costello syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.12866423).

BS2

High AC in GnomAdExome4 at 16 AD gene.
